Trainer Introduction:

Your trainer brings over 21 years of experience in operation & maintenance, erection, testing, project management, consultancy, supervision, substation automation, SCADA, and commissioning. With a background spanning power plants, high voltage substations, and HVDC installations, he has worked with renowned organizations such as Siemens Saudi Arabia. He has been involved in over 20 high-voltage substation projects across Pakistan and Saudi Arabia. His expertise encompasses a wide range of areas including protection systems, substation automation systems, design, testing, and commissioning of power generation systems, high voltage switchgear, protection relays, and control schemes. He has a proven track record of leading testing and commissioning teams for implementing electrical infrastructure projects for industrial clients, including steel and petrochemical industries. Course Details: Welcome to the course of “Single Line Diagram”. In power engineering, a single-line diagram (SLD), also sometimes called one-line diagram, is a symbolic representation of a three-phase electric power system. The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. Instead of representing each of three phases with a separate line or terminal, only one conductor is represented. Whenever it comes to start new project, define scope of work, Single line diagram is always the most important document to consider & prepare. Furthermore single line diagram is also required to prepare shutdown / maintenance method statement. Following topics are covered in this training: Introduction to Single Line Diagram Three Line Diagram What is difference between single line and three line diagram How to represent different element in Single line Vs three line diagram Components of Single Line Diagram, we will see how these components are shown in drawings and how these components actually looks like.
